IMPACT OF LANGUAGE LABORATORY ON ACHIEVEMENT AND RETENTION OF CHEMISTRY IN SENIOR SECONDARY SCHOOL STUDENTS IN BOSSO LOCAL GOVERNMENT AREA OF NIGER STATE

Abstract

The research investigated the impact of language laboratory on student’s achievement and retention in some concepts in chemistry at senior secondary school in boss local government of Niger state. A quasi-experimental design of the pre- test post-test won equivalent research design was adopted. Four research questions and four hypotheses guided the study. A sample of 72 SSII students (32 males and 40 females) was selected from two schools. Test (test blue print and the test item (CAT) were face and content validated by experts in the field). Two instruments were used for data collection. They are chemistry achievement test (CAT) and Chemistry Retention Test (CRT) the reliability of the interment using kuder Richardson formula 21 (KR-21) and the reliability coefficient of 0.09 was obtained. It was formed that language laboratory is more superior to conventional lecture method in terms of student achievement and retention. It terms of gender male and female students taught with language laboratory achieved and retained almost equality. Finally it was recommended that language laboratory should be used in classrooms and should be regular workshops and in service training for teachers on the use of language laboratory and the need for adequate supervision to ensure effective implementation of chemistry curriculum
